The project proposes the use of original synthetic methods to design and prepare: (i) polyoxometalates (POMs), (ii) POMs-based metal organic framework (POMOFs), (iii) metal-organic frameworks with electroactive ligands (eMOFs), (iv) layered double hydroxides (LDHs) and (v) heterostructures with layered double hydroxides.
The general objective is the synthesis, using original eco-friendly synthetic approaches, of catalysts based on layered double hydroxides (LDHs) and metal-organic frameworks with electroactive ligands (eMOFs) and polyoxometalates (POMOFs). To attain this objective, we propose three specific objectives: (i) Design and synthesis, using DESs and LMPLs, of novel POMs and POMOFs with transition metals. (ii) Design and synthesis, using DESs and LMPLs, of MOFs with electroactive ligands (eMOFs) and transition metals. (iii) Design and synthesis of LDH-based catalysts and LDH-based heterostructures for energy-conversion reactions by combining the most recent synthetic methods, including defects and vacancies creation.
The main original aspects of this proposal are: (i) The use, for the first time, of deep eutectic solvents (DESs) to prepare POMs, POMOFs and eMOFs,
(ii) The use, for the first time, of low melting point ligands (LMPLs) to prepare POMOFs and eMOFs with different transition metal ions and lanthanoids, (iii) the use of solvent-free mechanochemical synthetic methods to prepare LDHs with high content of defects for catalytic purposes.(iv) The use of basic etching techniques to create vacancies in LDHs and heterostructures with LDHs. (v) The study of the chemical reactivity of single crystals (SC) of eMOFs and POMOFs towards different gases and vapours to check for potential SC-SC transformation and dissolution-recrystallization structural transformations.
The project assumes as starting hypotheses that: (i) Combination of electroactive ligands and POMs with different transition metals may lead to eMOFs and POMOFs with catalytic activity towards different energy conversion reactions. (ii) The use of DESs and LMPLs may lead to highly porous eMOFs and POMOFs with novel structures and high catalytic activity. (iii) It is possible to replace toxic and harmful solvents with greener solvents such as DESs and LMPLs and solvent-free methods to reduce solvent residue generation. (iv) LDHs materials have tuneable band gaps in a wide range thanks to their unique structures, composition, single-atomic dispersion metallic cations, good catalytic activity, low cost and low environmental impact.
The project foresees a series of expected contributions that could have a key role in future research in synthetic MOF and POMOF chemistry and green chemistry approaches for the synthesis of MOFs and POMOFs with catalytic activity.
The prepared materials will be studied to test their thermal stability, gas sorption capacity, reactivity towards gases, vapours and metal ions and their catalytic activity towards different kinds of reactions, including energy-conversion reactions.
